Being honest Heli1, i don't imagine crushing the airframes is as much of a big deal as it would have been just few years ago. There will be comprehensive CAD and FE and CFD models of the aircraft which would be the starting point for future development/resurection. The hardest part would be if the manufacturing jigs were destroyed, but i'm not sure Comanche had got that far (don't remember the phase gate decision structure used). The individual prototype build up would have been photographed and documented, and i suspect this still exists. The biggest problem when a project like this is scrapped is that the expertise loses morale and goes elsewhere - do i remember a certain test pilot going fixed wing?
Mind you, given the circumstances it is well understandable.
